NDIS specs

Hi ppl

I am making an NDIS intermediat driver sitting above the Miniport driver
implemented on the LAN card. I need some documentation or reference of a
book which I can read to get started. I have the NDIS specs given by the
DDK documentation but as such it gives no examples. Please guide me
through.

Arijit

Hi

I think you can reer the sample codes given along with the DDK. I have
developed a Miniport Driver using these sample codes as reference. I think
this must be helpful.

You can find one intermediate driver for NDIS in Windows 2000/XP DDK

Under

%WINDDK%\2600\src\network\ndis\mux\driver

There are two types of NDIS intermediate drivers:

  1. Filter intermediate drivers
  2. MUX intermediate drivers.

Look into DDK “Passthru” sample which is a Filter IM, and “Mux” sample which
is a MUX IM.

Hi

thank you ppl…would take a look into the site and the example. Another
question is bothering me. I need to develop a NDIS intermediat driver
which would do some kind of packet filtering. Is it advisable to develop a
filter intermediat driver or is it possible to do it with an n to 1 mux
intermediat driver? If it is possible, then what are the tradeoffs
associated with each of them? I am asking specifically in context of the
problem that lies in front of me.

Thanks again for ur pointers…waiting for some more :slight_smile:

With regards
Arijit

These 2 types are different in INF file and registry setup only.

Filter IM means - 1-to-1 relation of upper and lower edges.
MUX IM means - any relation of upper and lower edges.

MUX is more complex. So, if your needs can be satisfied by Filter - use Filter.
Otherwise, use MUX.
